IMPROVEMENT IN DRYING LOAVES OI' SUGAR.

TO-ALL WHOM IT MAY CONGERII:

Be it known that I, vWILLIAM MORRIS DAVIS, of the city of Philadelphia,and State of Pennsylvania, have invented a new and useful Improvement inthe Process oi' Drying Leaves of Sugar; and I do hereby declare that thefollowing is a clear and exact description of the manner of carrying onsaid process, reference being had to the annexed drawings, making a partof this speciiication, in which- Figure l is a vertical section of aloaf of sugar, A boing a. hole or opening through the loaf' of suitablesize for the passage of a current oiwarm air.

Figure 2 is a perspective view of the loaf.

Figure 3 is a horizental View of the base of the loaf, A being thehollow or opening above described.

IIerotofore, in sugar refineries, on account of the time required to drythe large loaves in what is called piece moulds, the processes of themaker of hard or stove-dried sugar were limited to the smaller loafmould from sixteen to twenty pounds, and ctettler from thirtydivc toforty-ivc pound moulds, which alone dry in the periods of rcincs, saysix days. VBy removing thoheart or centre of aloai' as large as thepiece loaf, Weighing eighty-five pounds, by a small rotary cuttingtable,bit, drill, or other appropriate tool, and allowing the ascendingcurrents of hot air to act interierly on the heart or centre of thelarge loaf, it will be more rapidly and thoroughly dried, and renderediit for the crushing and pulverizing-mills, to the manifest great savingof labor and cost of implements. I prefer to make the hole along thevertical central axis of the cone oi' sugar, and for a piece loaf, whichis about fifteen to seventeen inches diameter at buse, I would make avertical cylindrical hole on said axis of two and one-half inchesdiameter. I prefer to drill `the hole through at that stage immediatelyafter the knocking out o'f'the loai' from thc mould, and before itspassage to the stove-room. ,lut the hole might be formed in some othermanner, and it might be'inadc in a different direction into or throughthe loailbut in any case the said hele, however formed, 'would expeditethe drying, although thc central axial hole through the loaf is deemedby ine tothe the best.

IIaving thus described my improvement, what I claim as my invention, is-

Forming a loaf of sugar with 'a hole through or into the interior of theloaf, for the purpose of expediting the operation ofidrying sugarloaves.
